About

LunaBill is building AI Voice callers for healthcare billing teams. Insurance claim follow-up calls account for the 80% of the daily workload of a healthcare billing team, with each call averaging 30 minutes. Since our launch in July we are now at $764K in contracted ARR, of which $428K is live revenue and the rest will go live by January 2026. Our customers see a 10x increase in claims followed up per biller in the first week and we have converted 100% of pilots to paying customers. We have automated 50,000+ calls and signed partnerships with top healthcare leaders like UC health systems, Mayo, Experian Health and more. The founders have known each other for over a year. Suhail is a 2x founder, with 3+ years of experience building in healthcare including operating a medical billing company with 200+ healthcare clients. David founded Skiesoft, Taiwan’s biggest healthcare AI scribe company, used by 120k+ healthcare professionals.

Automating claim-status calls, follow-ups, and reprocessing, so your billing team can finally focus on revenue, not hold music.

LunaBill builds AI voice agents that automate insurance calls for healthcare billing teams, handling claim-status checks, appeals follow-ups, and reprocessing. The agents connect to billing software, run up to 100 concurrent calls per client, and provide post-call workflow summaries, aiming to reduce manual dialing and accelerate A/R recovery.
